The headline tag was a keyword or phrase used to describe the topic and content of the article to help readers better understand and search for the article. Adding the headline tag to the article could help increase the exposure and reading rate of the article. The following steps must be followed when adding tags to articles: 1 Read the rules and guidelines of the headline platform to understand which tags are allowed and which are not. 2. Choose the appropriate tags according to the topic and content of your article and add them to the article title and content. 3. Often update and improve articles so that the headline platform can automatically identify and add new tags. It is important to note that the number and type of tags should be moderate. Overusing tags may reduce the exposure of the article.
